Application filed September 18, m5. Serial No. 278,851.

To all whom it may concern: l Be it known that I, GE RG F. DE WEIN, a J citizen of the United States, residing at Milwaukee, in the, county of Milwaukee and State ofW'isconsin, have invented certain new and useful. Im rovements in Water? Wheel Nozzles, ofw ich the following is a specification;

This invention relates to certain improvej ments in nozzles, and more particularly to a nozzle which is pressure-balanced; that is, where there is no reactive :fcrce tending to swing the nozzle. The nozzle is also mounted so that the reactions on the two pivot pins 0 carrying the'nozzle aree'qual, This nozzle has great value whennsed with water wheels driven by greatheads, thus re? sulting very' high pressures. -When "so used it is desirable to lcontrol the outlet, as

swinging the nozzle about its -pivot mounting to direct thefii, 'd against or away from the buckets. This lattcrcontrolmay-he a hydraulic relay governor,andwhen so connected upthe swingingiis automatic'. The disclo. sure is applied in this relation,--and in the drawings,-'Figure 1111's an: elevation ofithe nozzle showing the water wheel dia'gran1 inatioally.

The discharge is controlled by the core 8 which has a point entering the ischargc. At its rear end this core passes throu h an opening in the wall of the nozzle, whic 1' opening, is between the ,two' curved-passages of the nozzle.

7. The combination with a conduit of a nozzle pivoted thereto at two oppositely disposed points, the discharge end of said nozzle being in line with its pivoted end sothat a center line drawn through thedischarge and pivoted ends of said nozzle would intersect its pivotal axis, a part of said nozzle between its disehargeand'pivoted ends being offset from said center-line, and a core extended into said nozzle adjacent the discharge end thereof.
